Breeding Alien Betta Fish
Breeding Alien Bettas can be exciting, but requires patience and experience.
Breeding Setup
Use a separate breeding tank with:
- Warm water
- Gentle filtration
- Floating plants
- Low water flow
The male builds a bubble nest before spawning.
Spawning Process
After courtship, the female releases eggs, and the male collects them and places them in the bubble nest. Once spawning is complete, remove the female to prevent aggression. The male guards the eggs until they hatch, usually within 24–48 hours.
Raising Fry
Newly hatched fry require tiny foods such as:
- Infusoria
- Vinegar eels
- Baby brine shrimp
Frequent water changes and stable temperatures are important for healthy fry development.
